Introduction: Collagen bears many applications in pharmacy and medicine, health and cosmetic products as well as food industry. In recent years, much attention has been paid to separation of collagen from marine organisms arising from the fact that its use in the diet is not restricted and triggers no risk of contagious diseases as well as religious restrictions. Moreover, fish collagen is uniq...
background: collagen, the most abundant protein in the human body, and as an extracellular matrix protein, has an important role in the fiber formation. this feature of the collagen renders establishment of the structural skeleton in tissues. regarding specific features associated with the collagen, such as, formation of the porous structure, permeability and hydrophilicity, it can also be use...
Skin aging is a biological process that is due to the reduction of collagen production and increase of multiple enzymes, including matrix metalloproteinase (MMPS), which degrade collagen. Chlorella vulgaris is a marine microalga and its beneficial effects on the skin make it a proper ingredient to be used in anti-aging products. In this study, the effect of C. vulgaris extract comparing to vita...

HIGHLIGHTS Marine collagen - spongin extract from specimens of the sponge Aplysina fulva. Spongin has physicochemical and morphological properties analogous to human collagen. is an alternative source for tissue engineering proposals.
abstract the third millennium has started, but the world is facing with serious challenges in achieving international security and peace. various human rights violations have lead the states to find means to protect human rights. also article 55 of the united nations charter introduces the respect to human rights and fundamental freedom as the most suitable ways to realize peace and security. ...
Background and purpose: Human gingival fibroblasts cultured on collagen membrane is an alternative treatment method in guided regeneration. This in vitro study aimed at evaluating and comparing the human gingival fibroblasts viability on two types of collagen-rich membranes. Materials and methods: Human gingival fibroblast cells (HGF1-RT1) were cultured on two types of collagen-rich membranes...
Background: With aging, the facial folds, grooves, and sagging tissue become more prominent. It is haracterized by loss of the collagen mass in the dermis and an increased array of elastin whirls in the deeper dermis. The aim of this study was to determine whether correction of nasolabial folds could be achieved using an allogeneic collagen product. Methods: Nine healthy volunteers participated...
Background: Surface properties of a biomaterial could be critical in determining biomaterial’s biocompatibility due to the fact that the first interactions between the biological environment and artificial materials are most likely occurred at material’s surface. In this study, the surface properties of a new nanocomposite (NC) polymeric material were modified by combining plasma treatment and...
anti-angiogenic/anxiolytic effect of chlordiazepoxide: evidence on dual activity for cancer patients
angiogenesis which is the recruitment of new blood vessels is a critical process in several chronic diseases and is an essential component of tumor or cancer progression. development of therapies aimed at inhibiting the angiogenesis, in combination with classical anti-cancer therapies, is among the most intensively studied approaches to treat the cancer. in this study the effect of chlordiazepo...
